CDS's are a form of insurance. It can be hard for someone not in the industry to see the importance of these as it doesn't affect yoru day to day life.
Just imagine your day to day life where you can't get any isurance at all.
No car insurance, no house insurance, no medical insurance.
That's the extreme case, in all likely hood the more likely scenario would be all your insurance tripling in price as no provider can hedge their risk vai reinsurance, etc.
To me issuance is very important and one of the pillars of modern society. If insurance going away, or atleast being inaccessible to 99% of the population that doesn't seem to be "terrible" to you then I'm not sure what explanation I can give you to help you understand :)
